FreeBSD : fetchmail -- 6.4.19 and older denial of service or information disclosure (cbfd1874-efea-11eb-8fe9-036bd763ff35)

high Nessus Plugin ID 152150


New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote FreeBSD host is missing one or more security-related updates.


Matthias Andree reports :

When a log message exceeds c. 2 kByte in size, for instance, with very long header contents, and depending on verbosity option, fetchmail can crash or misreport each first log message that requires a buffer reallocation.


Update the affected packages.
